This invention relates generally to dental devices and is concerned more particularly with a stock card upon which artificial teeth are mounted and transported by the manufacturer to the dealer for sale to the dentist.

A principal object of the present invention "is to provide an improved stock card in which a main bodymounts the artificial teeth, and in which a single detachable insert identifies the artificial teeth independently of the main body. t i

Another object of thepresent invention is to provide such astock card wherein sets of different teeth maybe interchangeably accommodated by the main body and each set identified by thecorresp'onding insert, as a consequence of which, whileit is necessary forth'e manufacturer to keep on hand a full complement of different inserts for identifying the teeth he has occasion to package, it is not necessary for him to keep on hand a corresponding number-of different main bodies because the one main body may be utilized for packaging any of the different type of'teeth.

And still another object of the present invention is to provide such a stock card which is exceedingly simple in design and constructiori aii'd 'wbichiscdmparatively simple and inexpensive to manufacture; f

Other objects and advantages of the present invention will appear more fullyhereinaften'it being understood that said invention consists substantially in the, combination, construction, location and general arrangement of parts, all as described in detail in the following specification, as shown in the accompanying drawing and as fully pointed out in the appended claims.

In the accompanying drawings:

Figure 1 is a perspective view of a stock card which embodies the present invention;

Figure 2 is a front view of the main body of the stock card of Figure l;

Figures 3, 4 and 5 are enlarged sections taken respectively on lines 3-3, 4-4 and 5--5 of Figure 2;

Figure 6 is the same as Figure 2, but the main body is provided with wax which secures the teeth against accidental displacement;

Figure 7 is a section on line 7 7 of Figure 6; and

Figure 8 is a front view of the stock card showing the main body and the insert in partially assembled condition.

Referring to the drawing, the stock card comprises a main body 10 in the form of an elongated bar which is generally rectangular in transverse cross section, and which preferably is made of transparent plastic material. The opposite end portions of the main body 10 are provided respectively with thin wall or web areas 11a--11a at the bottom of rectangular depressions 1111, and the intermediate portion of the main body 10 is provided with a comparatively thick wall or web area 13a at the bottom of a rectangular depression 13. While the depressions 11--11 are formed in the face of the main body 10, the depression 13 is formed in the back thereof, as a consequence of which there extends about the periphery 2,874,487 1 Patented Bela 24, 1959 of the main body 10 a. heavy rib having parallel longitudinally extending portions which are designated by the numerals 14 and 15 and parallel transversely extending portions which are designated by the numerals 16 and 17.

The bottom surfaces of the depressions 11--11 are disposed in coplanar relation and in rearwardly spaced relation to the plane'of the bottom of the depression 13. At'. the opposite ends of the depression 13, extending transversely between the ribs 14 and 15, there are a pair of slots 18--18 through the medium of which the depression 13 communicates with the depressions 11-11. For detachably securing teeth to the main body 10, the latter is provided with a bed of pliable wax 19 or other suit able material which is disposed ina depression 12, the intermediate portion of the main body 10 being provided with a number of elements 20 which project into the depression 12 for securing the bed of wax 19jagainst displacement. It will be'understood that the term wax as employed in this specification and in the claims is intended to embrace any pliable material which is self-adhering in position and which also actsto adherently secure in position the teeth pressed into the exposed surface thereof.

The stock card of the present invention also comprises an insert 21 in the form of a rectangular member preferably made of heavy paper and having printed thereon all of the. information necessary to identify the teeth 22 mounted on the stock card. For example, the legend across the'top of the insert indicates the part of the mouth for which the teeth are intended and the type of teeth, and the legends at opposite ends of the insert indicate respectively the color shade and form of the teeth. The width of the insert 21 corresponds to the clear distance between the ribs 14 and 15, and the length of the insert 21 corresponds to the clear distance between the ribs 16 and 17. The'insert 21 is assembled with the main body 10 by'threading the same through the slots 18-18, and when fully assembled, the intermediate portion of the insert 21 is disposed in underlying relation to the comparatively thick bottom wall or web area 13a of the depression 13, the legend across the top thereof being visible through the transparent material of which the main body 10 is made, and the opposite end portions of the insert 21 are disposed in overlying relation to the thin bottom walls or web areas 11a11a of the depressions 11-11, being fully exposed to view.

Normally a manufacturer handles more than one type of teeth. If he utilizes the stock card of the present invention for packaging the same, he must have a full complement of inserts on handa different insert for each type of teeth. However, there is no need for keeping on hand a corresponding number of different main bodies because the main body of the present invention may be utilized for packaging any type of teeth. The reduction in the total number of main bodies required to be kept on hand and the resulting economy should be obvious.

It will be understood, of course, that the present invention is susceptible of various changes and modifications which may be made from time to time without involving any departure from the general principles or real spirit thereof. For example, the main body may be made of an opaque material. In this event the holder can be used for teeth of a general type identified by reference to a guide furnished by the manufacturer, the sub-type being identified by the legends at opposite ends of the insert. Accordingly, it is intended to claim the same broadly, as well as specifically, as indicated in the appended claims.
